In its announcement, the Korean automaker said that because of
the limited screen size, users will be able to see only things
like maintenance notifications. Hyundai's Blue Link mobile app
will connect Glass to features like remote remote start and
vehicle finder.

That sounds like one of my favorite car features, the head-up
display. It projects things like speed, navigation directions,
and local speed limits onto the windshield of a car, in the
driver's line of sight. It's a safe and convenient way to convey
important information, and eliminates the need for annoying voice
commands or taking your eyes off the road to look at a screen.

The problem is that head-up displays are heavy and expensive, so
they are offered almost exclusively in premium cars.

It shouldn't take much work to put information like navigation
directions and vehicle speed on Glass or a competing
technology. That would yield the benefits of a head-up
display, without the extra cost (after you buy Glass, of course).

Even if we can't get rid of huge touchscreens in cars (they're a
big money-maker), we can benefit from access to crucial
information without taking our eyes off the road.
